Switching Views within UITabBar View

I have created an UITabView application. Each view selected from the bar is a seperate controller with own ni开发者_JS百科b file. I switch between them succesfully.

In the first view I have two buttons (check out the screenshot). When clicking them I want to switch to another views which are the parts of the current view controller. I use:

[self presentModalViewController:anotherViewController animated:NO];

That switches the view, but hides the UITabBar. How to keep the bar on the screen after the switch?

P.S. Sorry for the blurred image. I am not allowed to share to much info.

Well I think you are misusing the modal view controller. For a problem like this I'll say you should put them in a view controller stack using UINavigationController. Instead of making each tab a UIViewController make it a UINavigationController, then you can push and pop view controllers on it, which still show the tab bar.
See http://developer.apple.com/iphone/library/documentation/UIKit/Reference/UINavigationController_Class/Reference/Reference.html

use: tabBarController.selectedViewController = newViewController

edit: UINavigationController is not needed here.
